Transport block transmission using different spatial parameters

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine a first set of parameters associated with a first transport block (TB) repetition of a TB and a second set of parameters associated with a second TB repetition of the TB; and determine a TB size of the TB based at least in part on the first set of parameters, the second set of parameters, or both the first set of parameters and the second set of parameters. Numerous other aspects are provided.
